I try to live by it but it's incredibly difficult. You're the consequence of all your past decisions, some of which will have been bad. You can go on to make better decisions, but sometimes it's the changes you make in light of past bad decisions which lead you on to make more bad decisions.

As for other's people's shit, as long as I like them, I do my best to not hold it against them, but it's resulted in some severe piss-taking in the past. If I don't like them, then no, forget it, total failure.
